Lightning strike and my thermostat

[Christian, Tommie and Dad]

Hi owners,
I have a 2017 17B. Lightning struck the utility pole near my RV and went to ground . Now the AC will not shut off and the thermostat shows a display, but will not respond to touch. I the have the Dometic capacitive touch thermostat for my AC and furnace. If anyone can help with tips on problem solving, removal and replacement of the thermostat, and thermostats you would recommend, then I would be grateful. We are planning a trip in October and I need everything working in my camper. Many thanks in advance for sharing your knowledge and experience.

I would first disconnect from electric and see what results. the plug back in and watch the results....

Yes, disconnect ALL electric including shutting off the 12V main switch on the face of a dinette bench.

So, a little update...the night of the strike I did unplug from the shore power and plug in again. No change, meaning AC ran full blast and thermostat showed a display but didn't respond to touch. I checked the breakers and all appeared ok, so wet, cold and tired, I went to bed.
Today I flipped all circuit breakers off and on. After this the system seemed to work, hooray. After letting the AC run for a few hours, the thermostat shows an E4 error. This indicates an open circuit or out of range outdoor temperature sensor. So, I will investigate more tomorrow.
